WKS-9
Single-Flange Explosion-Proof Differential Pressure Transmitter
A single-flange differential-pressure transmitter for sealed-vessel level and process-pressure service. It combines local LCD configuration, 4-20 mA with HART, 304/316 flange options, and a tantalum diaphragm option for strongly corrosive media.
Configuration note
Confirm the measuring range, medium, wetted materials, process connection, output, and power supply before ordering.
Technical selection overview
Use the published values below as a starting point, then confirm the complete measuring point before ordering. Final range, materials, connection, output, supply, and environmental limits depend on the selected configuration.
Integration and commissioning
Integrate the high- and low-pressure ports with the process or airflow system, then connect the configured analog or digital output to the control system. Confirm static pressure, differential range, manifold arrangement, and diaphragm material.
Equalize or establish a verified zero condition, confirm high/low port direction, apply known differential-pressure points, and test alarm or control behavior at operating thresholds.
Differential and static pressure
Choose a useful DP span while confirming that both ports and the sensing element tolerate maximum line and static pressure.
Pressure path
Define high- and low-side connections, tubing length, manifold arrangement, drain or vent points, and protection from condensate or blockage.
Zero and signal
Confirm bidirectional requirements, zero adjustment, response filtering, output scaling, HART or RS-485 integration, and alarm behavior.
APPLICATION FIT
Where this product family is commonly evaluated
- HVAC filters and airflow proving
- Cleanroom pressure relationships
- Tank level with differential pressure
- Primary flow-element measurement
Suitability is configuration-dependent. Review media compatibility, operating limits, installation conditions, required approvals, and the receiving control system before final selection.
